Tantrum Without A Cause

Somedays my baby is a Crabby-Patty. She wants up onto the couch and just doesn't want to do it herself so she has a tantrum. This video clip goes on for about two minutes, but the tantrum goes on for much, much longer than that! There is no reason to be crying and clawing at me and I refuse to give into her and pick her up when she acts like this so we have to just wait it out...Why did no one warn me about tantrums? I lay the blame on all you grandparents for this one!
